NGK has been saying point blank that using the most efficient spark plugs(are those exotic spark plugs most efficient anyway) will not dramatically increase the engine's power. You may expect at most 1% to 2% of your total engine output or 0.025% to 0.050% power increase to push the engine pistons.

Rather, the main effect is in the restoration or maintenance of the peak efficiency of the engine.
Sa experience ko, mas Ok talaga yung G-power sa car ko at di na ako babalik sa stock.
Gusto ko rin sana i-try yung IRIDIUM pero though my desire is strong my wallet is weak, so pass muna.
